daysUntilStale not being strictly enforced, plus surge of notifications within periods of calm
Hi. Thanks for this bot. It really helps.
I've got a question. If I have daysUntilStale=7, why do I often get situations like this, where the stale bot intervenes in an issue a few days after the 7 days mark has passed?
See how in the example below, the bot commented 13 days after the last activity.

OTOH we've noticed surges of stale-bot notifications. That is, we have days without any activity, and then days when there's a significant surge. I'd rather have a few notifications coming in daily than having days with all the notifications from the past few days all at once.
We've noticed the same thing, and ended up switching to a scheduled GitHub action (https://github.com/actions/stale). This is just my personal theory, but I'm suspecting that GitHub changed an API and stale-bot now has to run in intervals instead of continuously like it did before.
